Secure, jam-resistant GPS receivers for tactical radios are being provided to Harris Corporation by Rockkwell Collins.

Rockwell Collins said Harris has ordered 5,000 of its MicroGRAM system, the largest annual purchase it has received for the system.

The Micrograms are being delivered over a period of three years.

"MicroGRAM enables Harris Corporation to meet military customer demands for embedded, secure GPS," said Mike Jones, vice president and general manager of Communication and Navigation Products for Rockwell Collins. "MicroGRAM protects warfighters from the growing jamming and spoofing threats on the battlefield, while enhancing survivability and mission success."

Jones said that Harris is one of the first major original equipment manufacturers to commit to using MicroGRAM to meet the Department of Defense's requirement to use Selective Availability/Anti-Spoofing Module (SAASM) technology in its products.

"Harris is pleased to continue our long relationship with Rockwell Collins as our provider of GRAM SAASM GPS modules," said George Helm, president, Department of Defense business, Harris RF Communications. "Integrating the MicroGRAM receiver into a number of our new tactical radios allows us to reduce the size and weight while extending the battery life of our products."

Rockwell Collins said MicroGRAM is the world's smallest, lightest, and lowest-powered SAASM-based GPS receiver.

Harris Corporation manufactures the Falcon family of tactical radios, used by U.S. and allied militaries around the world.
